Part# PB1203-ST ; Powerbond performance street OEM style balancer for the Ford Windsor engines.  302 & 351 ci 8 cylinder V8 motors

This part number is for the 3 bolt pulley 28 oz. in. and Raised lower pulley location OEM balancers, typically the earlier 289 and 302 engines from 1965 to about 1969 here in Australia were the countersunk style lower pulley. However about 1969, 70 when the 351 Windsors were introduced here, some of them used cleveland water pumps and different pulleys so the lower balancer had a raised section, some were 3 bolt like this one and others were a 4 bolt.

IMPORTANT: match up these measurements becasue there are more than 6 styles of balancers for the Windsor engines. Diameter = 6.5 inch, Overall depth = 3.18 inch, & Balance ring width = 1.39 inch

Better than the stock OEM engine balancer for tough street strip engines or some limited spec racing. Precision high pressure long cure, hot bonded rubber balancer eliminates slipping and component separation, giving reliable performance on engines spinning up to 6500rpm. Counter Weighted hub balance.
